As we progress through the reproductive stage of the growing season, many growers have reason for optimism in terms of yield. But, even for those who are having a good year so far, stress from excess heat can have a negative impact on the crop. Agricen’s Scott Lay sat with Dennis Michelsen of WITY Radio to discuss how TERRAMAR can be applied with fungicide to help protect existing yield potential from heat and other weather-related stress.

Dennis - WITY Radio: It’s been a weird year with the weather. I believe all of those different weather factors are adding to crop stress, and we've already had a prolonged period of hot nights.

Scott - Agricen: In the summer months, heat will happen in every zip code, in every crop. It's a matter of trying to protect the yield potential that exists. With TERRAMAR, we have a technology that can help minimize the impact of heat stress on a crop. It’s a good day for a crop if you can minimize the temperature within the crop canopy. What we're seeing in a number of replicated trials is that we can reduce the crop canopy temperature by two to four degrees Fahrenheit with TERRAMAR.

Dennis - WITY Radio: We know we're going to get more heat going forward. How much benefit is there to applying TERRAMAR with fungicides?

Scott - Agricen: Let's review the negative detriments of heat on a crop. We know it impacts the ability of that plant to photosynthesize and to transpire water, and we know that it affects the plant's ability to mobilize nutrients into the plant and fill grain. So, if we can minimize that canopy temperature by two to four degrees with TERRAMAR, that's a positive. Secondarily, if we can increase the amount of nutrient uptake or movement in that plant, that's also a positive. We have documented a nutrient increase in tissue samples in the range of 10 to 15% with TERRAMAR.

Dennis - WITY Radio: Does that translate to yield?

Scott - Agricen: More often than not, it does. But more importantly, at each stage of the game, including the reproductive stage where we are today, we're attempting to increase the amount of nutrients available for that plant—to move starches and sugars to form that grain. If we can do that, we have a better opportunity to yield.

Dennis - WITY Radio: If you look at our weather this year, we had a lot of different weather conditions – from really wet to really dry, and with wind and hail damage in some parts. Now we take that already stressed-out corn, and we add more heat. Is there a cumulative effect of stress on a plant?

Scott - Agricen: I think there is a compounding effect. As we reach the critical reproductive stage, whether it be in corn, soybeans or perhaps other crops, fungicides are often applied to minimize the impact of disease, and that's a step in the right direction. But for factors brought about by the weather, TERRAMAR, in concert with a fungicide, provides a synergistic effect. If we can minimize the impact of a disease like tar spot, gray leaf spot or northern corn leaf blight with a fungicide, while also minimizing the canopy temperature of the crop with TERRAMAR to increase photosynthesis and nutrient uptake, the cumulative effect is positive. We're attempting to preserve yield potential, and we believe that's our best opportunity to do so.

Dennis - WITY Radio: With grain prices where they are, a producer I spoke to recently said he is changing his strategy this year to ensure he can get every additional bushel, because he needs that to make money this year.

Scott - Agricen: Corn and soybean commodity prices are not what they were a year ago, and certainly not what we would like them to be. The only other lever that can be pulled to impact net farm income is the yield. Again, we're not going to increase yield at this point. We're simply trying to preserve what yield potential exists. So if the crop is worth investing in to preserve yield potential, fungicide plus TERRAMAR gives a very consistent payback in terms of return on investment.

Wheat growers commonly apply fungicides to their crops to optimize plant health and yield. Typical application timings include early April after the flag leaves emerge (Feekes growth stage 9) and at heading shortly after (head scab application/Feekes growth stage 10.5.1). TERRAMAR can be utilized in the same pass as a wheat fungicide during any application timing, offering another stress-fighting and yield-enhancing tool to optimize crop yield potential.

What benefits can TERRAMAR add to a wheat fungicide application?

• TERRAMAR minimizes the impact of weather-related stresses (e.g., cold and dry conditions) to help maintain normal physiological functions. 
  
  
• TERRAMAR increases nutrient uptake and photosynthetic capacity at a critical time of yield determination.

Nutrien Ag Solutions has conducted multiple field trials in which TERRAMAR was applied at different stages of wheat growth with a fungicide. As seen in the examples below, consistent yield responses and a positive return on investment (ROI)* were observed across the different timings, whether one or multiple applications of TERRAMAR were made with the grower’s standard practice (GSP). 

FLAG LEAF/FEEKES 9 FUNGICIDE APPLICATION

In a Wisconsin field trial, TERRAMAR was applied at 1 quart/acre with fungicide at the Feekes 9 growth stage (flag leaf). The addition of TERRAMAR to the grower's standard wheat fungicide program led to a +3.62 bu/a yield advantage compared to the fungicide alone, with an ROI of 2:1.

(If a flag leaf fungicide application is not being made, TERRAMAR is also compatible with herbicide applications made at Feekes 8.)

HEAD SCAB SPRAY/FEEKES 10.5.1 FUNGICIDE APPLICATION

In a field trial in Michigan, adding TERRAMAR to the grower's head scab fungicide application led to a yield advantage that ranged from +3/9 bu/a (Plot 1, ROI of 2:1) to +12.8 bu/a (Plot 2, ROI of 7:1).

In an Indiana trial, the yield advantage when TERRAMAR was applied with a wheat head scab fungicide was +9.41 bu/a, with an ROI of 5:1 compared to the fungicide alone. 

In Ohio, a yield advantage of +12.0 bu/a was seen when TERRAMAR was added to a wheat head scab fungicide application, with an ROI of 7:1 compared to the fungicide alone. 

FEEKES 8, 9 & 10.5.1 (3 APPLICATIONS)

Lastly, a Pennsylvania field trial in wheat showed an +18.0 bu/a yield advantage when TERRAMAR was applied at 1 pint/acre at three time points: First with herbicide at Feekes 8, and then with fungicides at Feekes 9 (flag leaf) and Feekes 10.5.1 (head scab spray). The ROI in this trial was 9:1.

SUMMARY

Whether applied to wheat or another row crop, a foliar application of TERRAMAR offers a flexible and cost-effective way to enhance plant health and improve yield.

How can farmers maximize every unit of UAN sidedress they apply to help them reach their maximum yield potential?

Watch our on-demand webinar, "Enhancing UAN Sidedress Efficiency to Optimize Corn Yield Potential," to learn:

• What conditions favor best responses from sidedress nitrogen applications
  
  
• How enhancing a sidedress nitrogen application can potentially help offset the impact of planting delays
  
  
• When growers should apply UAN sidedress for optimal benefits
  
  
• How EXTRACT PBA can maximize the impact of UAN sidedress applications to optimize corn yield potential

Not all forms of nitrogen in UAN are readily available for crop uptake when applied. EXTRACT (6-0-0-13S), a combination of a fertilizer biocatalyst and ammonium thiosulfate (ATS), can improve the efficiency of UAN sidedress applications by influencing the two most important sources of plant-available nitrogen: the applied UAN and the residual soil nitrogen.

Accelerating the conversion of the urea component (50%) of UAN and positively affecting the mineralization and recycling of organic nitrogen in the soil are two key mechanisms in nitrogen use efficiency that lead to more available nitrogen from both applied and residual (already on/in the soil) nitrogen sources. Increased nitrogen availability combined with a more efficient use of nitrogen equals better growth potential, both immediately after EXTRACT application and for weeks to come in the growth cycle of the crop.

EXTRACT is also compatible with other technologies that enhance liquid sidedress nitrogen applications, such as BLACKMAX 22, an organic acid-based product that can be applied in tandem with liquid nitrogen to improve nutrient availability and support positive soil attributes.

Whether applied alone with UAN sidedress or with other sidedress-enhancing technologies, EXTRACT helps ensure that crops can access nitrogen during peak demand and that farmers can get the most out of their UAN sidedress investment.

Early in the summer of 2023, widespread nutrient deficiencies were observed in the Corn Belt, particularly potassium (K) deficiency in corn. Due in large part to drier-than-average early season growing conditions, abiotic stress—or stress from environmental conditions—was more prevalent, impacting crop physiological development and reducing nutrient uptake during a critical phase.

Beginning in mid-June, a number of crop consultants were reporting an interesting phenomenon. Corn fields treated with a foliar application of TERRAMAR in the V3-V7 growth stage visually appeared to be healthier and were not exhibiting the same level of K deficiency symptoms as untreated corn.

As a result of these observations, trials were conducted on later-planted corn in Minnesota and Michigan, and on a soybean field in Indiana to evaluate the impact of a V4 application of TERRAMAR on nutrient uptake and abiotic stress reduction. Corn nutrient demand significantly increases after the V4 window to produce a healthy, high-yielding crop.

In the Minnesota trial, a foliar application of TERRAMAR (1 quart/acre) was made at V4, followed by rigorous tissue sampling to determine nutrient uptake levels of treated versus untreated plants. A total of 135 tissue samples were taken at the V9 growth stage (10 days after application) hourly over a 12-hour period (7 am to 7 pm). In addition, leaf surface temperature readings of treated and untreated plants were taken to evaluate canopy temperatures. Higher ambient air temperatures during the trial period were an indication that the corn crop was experiencing moderate heat stress.

Compared to the untreated corn, TERRAMAR increased the uptake of the majority of nutrients into the corn leaf tissue (Fig. 1). Potassium uptake was particularly notable, showing a 38% increase compared to the untreated corn.

Fig. 1. Percent increase in micro- and macronutrients in corn tissue with TERRAMAR treatment versus untreated. Samples taken 10 days after foliar application of TERRAMAR.

Leaf canopy temperature was also notably reduced in corn that had been sprayed with TERRAMAR compared to the untreated corn (Fig. 2). Lower leaf temperatures indicate that the plants were under less stress and were therefore able to more efficiently perform physiologic functions such as transpiration and photosynthesis.

Fig. 2. Tissue temperature in the leaf canopy of corn plants treated with TERRAMAR versus untreated. Temperatures taken using thermal camera 10 days after foliar application of TERRAMAR.

At harvest, the TERRAMAR treatment was associated with a yield advantage of +11.2 bushels/acre compared to the untreated corn (165.8 bu/a vs 154.6 bu/a, respectively).

These results are in line with prior research demonstrating TERRAMAR’s consistency in reducing stress from abiotic factors (e.g., heat, drought, salinity, wind, hail and wet environments) at any given time in the growing season following a foliar application.

While stress mitigation significantly contributes to the product’s performance, more recent research indicates that a foliar application of TERRAMAR also increases nutrient uptake (documented by leaf tissue tests in both stressed and non-stressed environments), nitrate assimilation, carbon fixation, and photosynthetic capacity. These benefits add value by providing more efficient nutrient uptake during the crop’s critical demand windows.

Every growing season creates a different set of challenges, but some things remain constant. Globally, 50% to 70% of crop yield is lost to abiotic stress factors. Taking measures to reduce the impact of abiotic stress and increase nutrient uptake throughout the growing season with new technologies like TERRAMAR provides growers a fighting chance to add more to their bottom line across a range of crops.

As growers finish putting this year’s crop in the ground, Agricen’s Scott Lay spoke with WITY Radio’s Dennis Michelsen about TERRAMAR, a foliar product designed to help crops increase nutrient uptake and better tolerate weather-induced stress.

Dennis - WITY Radio: It’s impossible to predict the weather long term, but we know that something will always put our crop under stress every growing season. Would it be fair to say that the main reason a producer would want to add TERRAMAR to their lineup is to reduce stress?

Scott - Agricen: That is the essence of it. Weather-induced stress is one of the greatest yield robbers that farmers face. Up until this point, short of going to church on Sunday and praying for more moderate temperatures and rain, there's not been a heck of a lot we could do to address stress.

TERRAMAR was new to the row crop market last year, during which nearly 2M acres were treated. It does two things. One, it has a biologically extracted kelp component that minimizes the effects of weather-related stress, such as heat, drought or early season cold. Secondly, it has a biologically extracted carbon component that stimulates the plant to pull in more nutrients to aid in chlorophyll production and photosynthetic capacity, as well as increase carbon fixation in the plant. In this way, TERRAMAR provides a one-two punch that equals a better chance for yield at harvest time.

Dennis - WITY Radio: How and when is this product applied?

Scott - Agricen: TERRAMAR is designed for post-emergent foliar application throughout the growing season. It can go out early in the vegetative stages with a post-emergent herbicide in advance of the stresses that will present themselves to the crop. Then, as we get into the reproductive stages where a fungicide is often applied for the purpose of minimizing the impact of disease, a dose of TERRAMAR at that time will carry on for at least two to four weeks to minimize the impact of weather-induced stress.

We can measure this by canopy temperature. Last year, we did a number of trials across Indiana, Michigan and Minnesota to quantify the impact of TERRAMAR on canopy temperature in both corn and soybeans. Throughout the course of a July day, we saw that the canopy temperature of plants treated with TERRAMAR was 3°F to 5°F lower compared to untreated.

If you can lower the canopy temperature, that plant will be more efficient in reproducing and filling.

Dennis - WITY Radio: That's the key, Scott, because we always think about drought as a big stressor of crops, but we also get those hot nights where the temperature doesn't drop much below 75°F. That plant needs all the help it can get to stay out of stress, or we're losing bushels.

Scott - Agricen: That is absolutely correct. Heat happens in every zip code and every crop, every year. If we can moderate the temperature of the canopy, we're minimizing the impact of heat. It's not a replacement for a 60° F night. But if we can minimize the impact of those warm July and August evenings and give that plant a better chance to photosynthesize and to transpire water and nutrients, again that correlates very nicely to better yield potential.

Dennis - WITY Radio: What's the ROI that we can expect?

Scott - Agricen: In third-party university trials and farmer-conducted side by sides, we’ve found that the average response is 7 to 10 bushels in corn, 4 to 7 bushels in soybeans and 5 to 8 bushels in wheat. All told, regardless of crop, the average is a 3 or 4:1 return on investment. So for every dollar invested in TERRAMAR, a farmer could expect a $3 to $4 return as a result of an increased yield result.

TERRAMAR is available from Nutrien Ag Solutions.

The use of starter fertilizer, aimed at getting plant nutrients in a concentrated zone close to the point of seed placement, is a common practice in some parts of the country.

A standard starter program for corn in the U.S. Corn Belt is 3-5 gallons of ammonium polyphosphate (10-34-0) plus 1 quart of zinc per acre. More progressive growers have gravitated towards readily available orthosphosphate blends containing micronutrients or other enhancements like biostimulants. Regardless of the rate, timing, source and amount (the “4Rs”) of the practice, the goal is the same: Get the most out of every nutrient applied for better early growth and development.

Conversion from polyphosphate to plant-available orthophosphate takes place in the soil, where microbes and soil chemistry both play a role in making the applied and existing soil nutrients available to the plant, as well as in the timing of nutrient release into the soil solution. For any liquid starter program to be successful, growers must consider several key factors like soil test values, crop yield goals, field conditions and potential for nutrient release when the crop needs them most.

Thankfully, growers don’t have to leave it all up to nature. By enhancing liquid starter programs with ACCOMPLISH MAX or PROLOGUE, growers can speed up the conversion process in the soil and facilitate plant nutrient uptake by providing highly available forms of nutrients. The outcome is improved plant performance, as demonstrated in the trials below.

ACCOMPLISH MAX

ACCOMPLISH MAX is specifically formulated for use with liquid starter fertilizers. It contains diverse biochemicals (e.g., organic acids, enzymes) that interact with liquid fertilizers and soil chemistry to improve nutrient availability and facilitate nutrient uptake by the crop. It also contains a kelp-based technology that helps crops better tolerate potentially yield-robbing stresses like cold temperatures, saline soil, heat or dry conditions.

In the corn trial below from Ohio, the grower standard practice (GSP) was an in-furrow program consisting of NPK, a micronutrient starter and Proven 40 (a microbial nitrogen-fixing product from Pivot Bio). This was compared to GSP plus 1 quart/acre of ACCOMPLISH MAX over three fields.

The results? Adding ACCOMPLISH MAX to the grower's standard in-furrow program led to a yield advantage of +6 bu/acre over the GSP alone.

In another example, a corn trial in Nebraska looked at the impact of adding ACCOMPLISH MAX at 1 quart/acre to a starter program consisting of Loveland Products’ Riser (2 gals/acre) and Black Label Zn (1 gal/acre).

The results? A visual difference with ACCOMPLISH MAX earlier in the season, including thicker stalks and healthier plants above ground, with deeper, more developed roots below. The early, healthier start resulted in a +4.5 bu/acre yield advantage at harvest compared to the starter program that did not include this technology.

PROLOGUE

PROLOGUE (5-0-0 6.3% Zn) is a combination of highly plant available zinc and nutrient solubilizing technology comprised of microbial metabolites (biochemicals) and active, phosphorus-scavenging microbes that colonize within the root system.

PROLOGUE fits any banded liquid phosphorus-based fertilizer program requiring supplemental zinc for optimal plant growth. It is formulated to increase the efficiency of both applied phosphate and existing phosphate bound in the soil, as well as balance the P:Zn uptake ratio. (For every 10 units of phosphorus, a plant needs 1 unit of zinc.)

In this corn trial from Kentucky, PROLOGUE was applied 2x2 with 10 gals/acre of 10-34-0.

The results? A yield advantage of +7.15 bu/acre with PROLOGUE in the starter program compared to the 10-34-0 starter alone.

Crops that get off to a good start often maintain an advantage during the growing season over those that struggle to get going. As these studies show, growers that include a technology such as ACCOMPLISH MAX or PROLOGUE in their starter programs—whether a polyphosphate, an orthophosphate/polyphosphate blend or other liquid starter—can maximize the efficiency of applied nutrients and improve crop performance.

Whether conditions are “ideal” or stressful, the key is to be prepared for whatever the growing season brings so that you can reach your yield goals.

In this on-demand webinar hosted by CropLife, "Stand Up to Stress for Higher Yield & ROI," you'll learn:

• What abiotic stress is
  
  
• How ag biologicals and biostimulants fit into crop stress and plant health management programs
  
  
• How TERRAMAR, a new foliar technology for agricultural crops, enhances plant performance while mitigating the impacts of abiotic stress

During the webinar, Dr. Connor Sible of the University of Illinois discusses common abiotic stresses, how biological and biostimulant technologies can play a role in addressing them, and, specifically, how marine extracts promote stress relief in plants. He also discusses the need for a proactive approach when it comes to application timing.

"Stress mitigating biostimulant applications need to be proactive, not reactive," says Dr. Sible. "The crop needs time to build the defense so that it is able to tolerate the stress when it arrives."

Agricen's Dr. Brian Cornelious follows his presentation with a discussion of TERRAMAR, which can be used to enhance nutrient uptake while improving crop tolerance to abiotic stress.

TERRAMAR is a unique combination of carbon- and marine-based components that have complimentary functions:

• Carbon-Based Technology (derived from biologically converted leonardite) enhances nutrient uptake and provides key carbon derivatives for additional energy to optimize plant performance
  
  
• Marine-Based Technology (derived from biologically digested kelp) improves crop tolerance to abiotic stressors such as heat, drought, salt, and cold

Exclusively available from Loveland Products through Nutrien Ag Solutions, TERRAMAR can be used in combination with early, mid-season, or late-season foliar applications (including foliar nutrition, insecticides, herbicides, and fungicides) to mitigate stress and improve nutrient uptake. Foliar applications deliver its unique set of highly active, metabolite-based compounds for quick absorption through the leaf tissue of the plant. Multiple field trials validate the effectiveness of TERRAMAR as an addition to crop protection and nutritional programs.

Watch the webinar to learn how to help your crops stand up to stress for higher yield and ROI.

Crops need phosphorus (P) early in their development to help them get off to a good start. This important macronutrient not only helps them capture and convert sunlight into useful plant compounds, it also assists with plant growth, stalk strength and early root growth and development.

One challenge that growers need to think about each season is that phosphorus availability can be limited by soil fixation, poor root growth and cold temperatures that limit microbial activity. Much of the phosphorus that is applied each season is at risk of fixation with elements in the soil like iron (Fe), aluminum (Al) and calcium (Ca). Once those bonds have formed, the bound phosphate becomes essentially unavailable to the growing crop. For these reasons, it is difficult to access phosphate in the soil bank, making applied phosphate relatively inefficient.

Along with phosphorus, plants also need zinc (Zn). Zinc plays a role in the manufacturing of plant hormones that help drive root growth. It also has a unique relationship with phosphorus, interacting with phosphate to influence root growth. These two nutrients work best when they are available in a ratio in which neither one is limiting the other. Unfortunately, prevailing spring conditions, like cool temperatures and waterlogged soils, can limit the availability of zinc.

PROLOGUE (5-0-0 6.3% Zn) is a unique technology designed to enhance phosphate nutrition for a higher performing and more sustainable approach to crop nutrition. In the trial below, adding PROLOGUE to 10-34-0 starter led to an average yield increase of +8.9 bushels per acre across six sites.

PROLOGUE combines the critical early season micronutrient, zinc, with unique nutrient solubilizing technology that increases the efficiency of both applied phosphate and existing phosphate bound in the soil. Working together, these components enhance early germination and crop growth, helping crops better absorb both applied nutrition and soil bank nutrition:

• Nutrient solubilizing technology - Microbial metabolites (biochemicals) and active, phosphorus-scavenging microbes that colonize within the root system to keep more applied nutrition available to the crop. They also help loosen the bonds of recalcitrant phosphorus in the soil to improve phosphorus availability during the growing season.
  
  
• Chelated zinc - A plant-available form of zinc.

Many crops can benefit from PROLOGUE, especially those that do best with an early season application of liquid phosphate (including ammonium polyphosphate or liquid phosphate containing blends) near the developing root system.

With technology that drives more phosphorus into a developing crop, PROLOGUE can help growers realize big dividends at the end of the season.

How can growers get the maximum benefit from existing and applied nutrition to maximize their yield and return on investment?

Watch our on-demand webinar, "Early Season Opportunities to Enhance Nutrient Availability with EXTRACT PBA," to see:

• How Extract helps unlock the nutrition crops need from the soil, organic and inorganic nutrient applications and the previous season's crop residue for maximum yield
  
  
• How to get the most utilization out of applied and residual nutrition with Extract
  
  
• Results from corn, soybean and wheat trials

Extract enhances nutrient release and mineralization from the soil, liquid fertilizers and crop residues, which promotes nutrient availability and uptake. It can be used with pre-plant liquid fertilizers, pre-emergent herbicides, UAN sidedress applications or fall burndown chemistries to unlock more nutrition for crops.  

In an analysis of 105 third-party and side-by-side trials conducted over the past decade, the average yield increase gained by utilizing Extract was +10.3 bu/a in corn (53 trials), +3.7 bu/a in soybeans (47 trials) and +5.5 bu/a in wheat (5 trials) as compared to no Extract treatment.

By giving crops greater access to the nutrition they need, Extract can help boost crop yields and increase a grower's return on investment.

Extract is exclusively available from Nutrien Ag Solutions.
